SPECIFICATION forming part of Letters Patent No. 281,456, dated July 17, 1883.

- Application filed January 4,1883. (No model) To all whom it may concern:

Be it known that I, GEORGE J. OLINE, a citizen of the United States, residing at Goshen, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Wrenches; and I do declare the following to be a full, clear, and exact description of the invention, 'such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a side view of my wrench. Fig. 2 is a side view of the shank B. Fig. 3 is a cross-sectional view taken through y y, Fig. 1; and Fig. 4 is a cross-section taken through 00 x. r

This invention has ,relation to slide jaw wrenches; and it consists in the construction and novel arrangement of the squared main shank, the lug-bearing having a square seat extending through it, the slide-j aw, its screwstem having bearing-shoulders near its pivotal ends, the handle, and fastening -nut, all as hereinafter set forth. i

In the accompanying drawings, the letter A designates the fixed jaw at the end of the main shank B, which is formed with square corners in the portion 0 next to said head, this portion being the bearing or guide on which th slide-j aw D moves.

At the lower end of the guide-bearing O a shoulder, e, is formed, below whichis a smaller squared bearing, g, on which the lug-bearing H is seated, a squared opening or seat, is, being formed through the same toengage the bearing 9 of the shank. Below the bearing 9 the shank extends through the handle L, and is threaded at its end to receive the fastening- I nut n.

In the slide-jaw D, in rear of the shank, are formed bearings m at, one of which is thread.-

ed to engage a screw, 8, the pivot or journal ends of which engagebearings in the fixed head A and in the lugbearing H, as indicated at o and o. Shoulders z and z are formed on the screw-stein, and these respectively engage the head A and lug-bearing H, so that the screw forms a brace, adding materially to the strength of the wrench. The journal on extends through the perforation o in the lugbearing, and is provided with a. milled head, w, which, being in rear of the lug-bearing at the upper end of the handle, is in position to be conveniently reached and easily turned by the fingers in manipulating the wrench.

It will be observed that a recess is formed in the lug-bearing H', to receive the milled head of the screw, and that said milled head is arranged behind that portion of said bearing which extends upward to receive said screw.. By this construction the milled head is brought within easy reach of the thumb and forefinger of the operator without removing his grasp upon the wrench-handle. Having describedthis invention, what I claim, and desire to secureby Letters Patent, 1s

In wrenches, the sliding j aw D, having bearings m and m, the screw 3, having shoulders z and z, and milled head to, in combination with the main shank and lug-bearing H, recessed,

as shown, to receive said milled head in rear of its raised flange, as shown, whereby the main shank is braced and strengthened, and the milled head is arrrnged within reach of the thumb and forefinger of an operator while his hand grasps the handle, substantially as specified. In testimony whereof I affix my signature in presence of two witnesses.
